help please with GCC compiler installation.
I found very detailed document on installation.
I follow instructions.
When I run configure I get:

[root@localhost objdir]# ../gcc-3.3.1/configure --prefix=/opt/gcc-3.3.1
Configuring for a i686-pc-linux-gnu host.
Created "Makefile" in /gcc3/objdir using "mt-frag"
../gcc-3.3.1/configure: line 8: cc: command not found
*** The command 'cc -o conftest -g conftest.c' failed.
*** You must set the environment variable CC to a working compiler.
[root@localhost objdir]#

How to set the environment...
Please provide detailed help.
Thanks.
Michael.

Are you trying to compile gcc from source?
If so you'll need a working compiler to do so first or follow the steps at the gcc homepage.
If you already got a version of gcc on there you'll find where it is with whereis gcc.
Normally its /usr/bin/gcc as a symlink to whatever version you got on there.

"export CC=/usr/bin/cc" should work (if that's where your cc lives).

You need a compiler to compile the new compiler.

Probably I don't have any compiler
I think I didn't install packages for development

It is recommended to run the configure script in a directory other than the source code directory so that the source code tree is completely separate from the place where you build thecompiler.

For the sake of this example, I have created a directory /gcc3/objdir and I ran the configure script from that directory. As you already know, the source code tree is under the /gcc3/gcc-3.0.4directory. You may need to add a prefix for GCC installation files. The pre-fix shows the directory where GCC files will be finally installed. The default prefix is /usr/local. This means that GCC binary files will be installed in /usr/local/bindirectory.
For installation purposes, I have selected /opt/gcc-3.0.4directory as the prefix. In a typical development environment, you would do something similar to that. Just create a directory under /opt and install all of your tools and applications under /opt. The following command line will configure the GCC compilation process and will create many files under /gcc3/objdir. These files will be used later on to build the compiler.

When you start the configure script, the following messages will start scrolling up.
[root@laptop objdir]# ../gcc-3.0.4/configure --prefix=/opt/gcc-3.0.4

If possible check please text in previous post.
I created directories exactly as explained.
May be I have to do something else for updating env....
